Abstract

By limiting the movement of the printing paper, a paper tension structure is disclosed which can stably maintain the conveyance of the paper even when the printing paper is moved forward and backward. The paper tension structure is a paper feed guide for supplying printing paper, a tension bracket that is rotatably mounted up and down on the side of the paper feed guide, and is mounted to be parallel to the printing paper at the end of the bracket to press the upper surface of the printing paper. It includes a tension guide. Due to the structure of the printer, a paper jam or meandering may occur in the process of feeding the printing paper forward or backward. Thus, the tension structure can press the upper surface of the paper by its own weight, and even if the paper is moved forward or backward, the paper can be prevented from being meandered from the conveying path or reentering.

Description

Paper Tension Structure {STRUCTURE FOR TENSION OF A PRINTING PAPER}

The present invention relates to a printer using continuous paper, and more particularly, to a paper tension structure for smoothly supplying printing paper in a printer using continuous paper.

In general, customers use the bank account to check the transaction history, and can also check the deposit and withdrawal details and other information through the voice call phone or banking transactions through the Internet. However, when inquiring the deposit and withdrawal details through the voice guidance phone has a disadvantage that the customer can not remember all of the large number of transactions. Of course, the transaction history can be output using the Internet, but this method also has a disadvantage in that a connection using a network and a separate printer must be used.

In order to output transaction details in a manner other than a bankbook, a method of outputting a transaction history based on a predetermined transaction history may be proposed. Since the automated teller machine is spread in public places, bank branches, convenience stores, etc., it is easy to access, and if the automated teller machine can provide transaction details, it can be easily proved in paper form without a bankbook.

In addition, the back of the paper provided for the transaction history can include a variety of guides or advertisements can be said to have a number of commercial advantages.

However, in order to provide transaction details in the automated teller machine, a large amount of paper must be stored in the automated teller machine, and the consumption of paper should be minimized as much as possible.

Conventional printers include dot printers, laser printers, inkjet printers, and thermal printers, and these printers generally use standardized A4 paper.

However, these A4 papers are forced to provide paper of the same size to all customers using the output service as individually separated papers, and as a result, there is a problem that the paper is severely wasted.

1 is a view for explaining a printer capable of supplying a double paper of the related art.

Referring to FIG. 1, two boxes 3 and 4 accommodate a continuous paper having a width of A4 or B5 in a folded state, and the first paper 1 and the second paper 2 are each a printer 10. ) Can be used to print the required work.

The first paper 1 and the second paper 2 may be classified into different formats, different sizes, different colors, and the like, and sizes and sizes of A4 or B5 paper may be different depending on the size of the paper to be cut. Depending on the size provided in some cut state may be used.

Folding continuous paper can be used by bending the continuous paper to a certain size. Folded continuous paper has the disadvantage that it may appear on the paper with perforations or bend marks in the middle of the paper, but the paper takes up a small volume, and even if you do not use a separate paper feeding structure, the box may be placed in a designated place. The advantage is that the setting is possible. On the other hand, the rolled continuous paper does not show a cut line or a bent line on the printed paper, but requires a separate structure for mounting the rolled continuous paper, and has a relatively large space.

First, as shown, the printer 10 uses a foldable continuous paper, and can perform the printing operation by separating the first paper 1 and the second paper (2). Specifically, the printer 10 includes a first transfer guide 20, a second transfer guide 30, a thermal print module 40, a cutter 50, and a stack transfer unit 60.

The first sheet 1 is provided to the print module 40 through the first transfer guide 20, and the second sheet 2 is provided to the print module 40 through the second transfer guide 30. The first and second transfer guides 20 and 30 are equipped with feed rollers 22 and 32, respectively, and the first paper 1 or the second paper (by the selective operation of the feed rollers 22 and 32). 2) can be supplied to the print module 40.

The print module 40 includes a platen roller 42, which supports the printing surface in correspondence with the print head, and on the other hand rotates and continuously conveys the printed portion of the printing paper. Function When the printing is completed, the cutter 50 cuts the printed portion, and the stack transfer unit 60 may transfer the cut printing paper to the stack space or discharge it to the outside.

As shown in FIG. 1, the driving units of the print module 40 and the stack transfer unit 60 are connected by one motor. Therefore, before conveying the cut printing paper into the stack space, the paper engaged with the printer module (a) must be conveyed backward, i.e., back-feeding.

In addition to this reason, when the second paper 2 is to be used next to the first paper 1, the other paper may be loaded by back-feeding the paper, and the print head and the cutter 50 may be loaded. Even if the waste of paper is heavy due to the large gap between them, the printing position of the paper can be adjusted through back-feeding.

FIG. 2 is a partially enlarged view for explaining back-feeding of printing paper, and FIG. 3 is a partially enlarged view for explaining reentry of printing paper.

2 and 3, the first roller 1 is also conveyed in reverse while the conveying roller 22 rotates in reverse. At this time, the first paper 1 may be pushed back and may rise to the center of the bent portion, and may be partially separated from the conveying path of the paper.

The conveying roller 22 may rotate in the forward direction to enter the first sheet 1 back into the conveying guide 20. However, since there is a high possibility that the first sheet 1 is partially separated, skew of the sheet may occur during reentry, and a paper jam may occur.

In order to solve the above problems, an object of the present invention is to provide a tension structure that can stably supply the paper by minimizing the separation of the paper.

Another object of the present invention is to provide a tension structure that can be simply set without any other material such as a spring, and is easy to implement as an operation using weight.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the paper tension structure is a tension bracket which is mounted to be movable up and down on the side of the paper transfer guide paper transfer guide for supplying printing paper, and the bracket And a tension guide mounted at an end portion of the printing paper so as to be parallel to the printing paper and pressing the upper surface of the printing paper.

The paper tension structure corresponds to the forward rotation or the reverse rotation of the paper, and the tension guide can induce the paper to pass through the predetermined route by pressing the upper surface of the printing paper. The tension guide includes a tension bracket mounted on one or both sides of the transfer guide, and the tension guide can be significantly reduced in the area in which the paper can be moved up and down by being fixed to the tension bracket or by connecting both brackets.

The tension guide may be rotatably mounted to facilitate the conveyance of the paper, but may be guided to the conveyance of the paper even if the tension guide is fixedly mounted to the tension bracket. In addition, the tension bracket may also be rotatably mounted with respect to the paper transfer guide, and may be mounted to reciprocate along a predetermined path even without rotation.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.
